– 2000-V Human-body model (A114-A)
The ST1G3236 is a dual supply low voltage
CMOS 1-bit bus Transceiver fabricated with submicron silicon gate and five-layer metal wiring
C2MOS technology. Designed for use as an
interface between a 3.3V bus and a 2.5V or 1.2V
bus in mixed supply systems of 3.3V/1.2V,
3.3V/2.5V and 2.5V/1.8V, the ST1G3236 achieves
high speed operation while maintaining low power
dissipation. VCCA and VCCB can be powered from
1.2V to 3.6V respectively. The DIR pin is designed
to track VCCB.
The device is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
DIR inputs.
All inputs are equipped with protection circuits
against static discharge, giving them 2kV ESD
immunity and transient excess voltage.

Maximum rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE

CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated
from the operating current consumption without load. (Refer to Test Circuit). Average current
can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/4 (per circuit)
